Question

You throw a ball from the balcony onto the court in the basketball arena. You release the ball at a height 𝐻 = 7.00 m above the court, with an initial velocity 𝑣₀ = 8.40 m/s at 𝜃 = 35.0∘ above the horizontal. A friend of yours, standing on the court 𝐷 = 11.0 m from the point directly beneath you, waits for a period of time after you release the ball and then begins to move directly away from you at an acceleration of 𝑎 = 1.90 m/s². (She can only do this for a short period of time!) If you throw the ball in a line with her, how much time 𝑡_wait after you release the ball should she wait to start running directly away from you so that she’ll catch the ball exactly 2.00 m above the floor of the court? The time I got was 2.3 seconds… but that's not correct. I just need a better understanding of how to write/use the equations for this projectile motion problem.
